This invention relates to hair curlers for use in producing permanent hair waves, and particularly in producing permanent hair Waves by the cold wave process.

Among the objects of the present invention it is aimed to provide an improved curler for use in producing permanent hair waves which contemplates the use of a chambered curling rod, a container for hair treating liquid disposed in said rod with openings in the rod to enable the liquid in the container to seep therethrough into contact with the hair wound upon the rod, and means associated with the rod for releasing the liquid in the container when desired.

More specifically it is an object of the present invention to provide an improved curler for use in producing permanent hair waves, particularly by the cold wave process, which contemplates the use of a chambered curling rod, a container for a combined lotion and neutralizer liquid disposed in said rod, with openings in the rod to enable the liquid in the container to seep therethrough into contact with the strand of hair wrapped around the rod, and means associated with the rod for releasing the liquid in the container when desired.

It is a further object of the present invention to provide an improved curler for use in producing permanent hair Waves, particularly by the cold wave process, which contemplates the use of a chambered curling rod, a fracturable container for a combined lotion and neutralizer liquid disposed in said rod, with openings in the rod to enable the liquid in the container to seep therethrough into contact with the strand of hair wrapped around the rod, and means in said rod for anchoring said container against rotation so that when said container is twisted relative to said rod when desired, the container will fracture and enable the contents freely to flow therefrom.

These and other features, capabilities and advantages of the present invention will appear from the subjoined detailed description of specific embodiments thereof illustrated in the accompanying drawings, in which Fig. 1 is a side elevation of the curler.

Fig. 8 is an exploded view of the liquid container.

In the embodiment shown there is illustrated a chambered rod i having a chamber 2 to receive the container 3 having the head 4. When the container 3 is disposed in the rod l the combined outer contour or conformation of the rod l and head 4 conforms to the conventional curling rod in outer contour. The rod l in the present instance has a knurled cylindrical end portion or head 5 from the outer end of which there extends a projection 6 having an opening 1 therein to receive one end of an anchoring cord 8, the other end of which cord 8 preferably has secured thereto a rigid button or enlargement 9. The portion iii of the rod intermediate the knurled portion 5 and the end i l recedes in accordance with convention. This receding portion is is provided with a number of openings which in the present instance are shown as six elongated slots I2 located so that they will be positioned directly beneath the strand of hair to be wrapped around the rod l, the slots 12 forming openings for the chamber 2. The inner end of the chamber 2 is provided with a transversely extending slot 13 to receive the flattened end M of the container 3 when the intermediate collar l5 snugly fits in the outer end of the chamber 2 with the inner end of the head i in engagement with the outer end ll of the wall of the chamber 2. In the claims the head 5 will be referred to as the first head and the head 4 as the second head.

The cylindrical surface of the head 4 also preferably is knurled as shown, with aplurality of conventional cord receiving notches l B in the end thereof.

The rod l and the head 4 may be composed of metal, preferably a light weight metal such as aluminum, or some suitable thermoplastic or thermosetting material that is substantially noninfiammable, such as a cellulose acetate, polystyrene, polymethyl methacrylate, ethyl cellulose, copolymer of vinyl chloride and vinyl acetate, urea formaldehyde, melamine formaldehyde or resins made from urea, butanol and formaldehyde. The container 3, however, to satisfy the present invention as disclosed in Figs. 1 to 7, inclusive, must be composed of some suitable fragile material so that after the container 3 has been inserted into the chamber 2 of the rod I with the flattened end 14 properly positioned in the slot i3 and the collar l5 positioned in the open end of the chamber 2, with the edge of the head 4 engaging the edge I! of the rod l, the container 3 may be broken or fractured so that its contents will be free to be discharged by merely twisting the head t and therewith the container 3 relative to the rod l, the recess l3 cooperating with the flattened end M to resist such twisting force and thereby permit the body of the container to be broken. For this reason the heads 5 and 5 are knurled so that the fingers of the operator may engage the same, as an instance, the fingers of the left hand holding the head 5 and the fingers of the right hand holding the head 4, and transmitting a twisting force to the head 5.

Excellent results have been achieved when the wall structure of the container 3 was composed of a thermoplastic or thermosetting material that would not splinter but would fracture readily, such as a cellulose acetate, polystyrene, polymethyl methacrylate, ethyl cellulose, copolymer of vinyl chloride and vinyl acetate, urea formaldehyde, melamine formaldehyde or resins made from urea, butanol and formaldehyde, and in aid thereof a weakened area was provided in the middle thereof, see as an instance the diminished annular portion [1.

In the use of this curler the container 12'- is preferably filled with a combined lotion and neutralizer liquid mixture of which the active ingredients are as an instance thioglycholic acid and a magnesium salt, or sodium sulphite triethanolamine and sodium hypersulphite, and the head 4 permanently secured to the container so that the contents can only be released by breaking the wall of the container 3. Thereupon a strip of tissue It about four inches by two inches, in accordance with convention, is folded around the end of the strand 19 of the hair to be wrapped around the rod l, and then the tissue I8 is wrapped around the rod i and the rod I rolled downwards relative to the scalp 2%] of the customer or patron in the direction of the arrow 2!. After the strand I9 has been completely wrapped around the rod l, in accordance with convention, then the cord 8 is laid over the top of the strand E9 of hair, see Fig. '7, and the end of the cord pressed into one of the notches l6.

Alter the strand is of hair has so been wrapped, I

the operator or attendant will twist the head 4 relative to the head 5 until the container 3 breaks, the cord 8 maintaining the container 3 in place in the rod 5 after such breakage, whereupon the liquid in the container 3 will be free to ooze out and seep through the openings l2 into engagement with the hair of the strand l9 until the hair has been thoroughly saturated. Some operators may of course also prefer to twist the head 4 relative to the head 5 before securing the cord 8 in a notch it. Such deviation from the aforesaid operation will of course be within the purview of the present invention. The time period requirement for retaining the rod l in place on the head of the customer or patron will of course depend upon the character of wave to be produced and the nature of the liquid mixture. While this curler is particularly adapted for the cold wave process when the liquid mixture consists both of a lotion and a neutralizer, it will of course be obvious that it could also be used with the conventional heating method heretofore extensively used without departing from the general spirit of the invention when the liquid content would consist only of the lotion and the neutralizer applied after the heat portion of the treatment has been completed.

According to the embodiment shown in the modification of Fig. 8, instead of using a container 3 which is breakable, the container 3 may of course be composed of two telescoping members, one within the other, such as the outer telescoping member 22 having the openings 2c and the inner telescoping member 23 having the washer 25, which openings 24 will be shut off in one position of the telescoping members 22 and 23, and be exposed when the member 23 is turned outwardly in another position of the telescoping members 22 and 23 relative to one another. If the embodiment shown in Fig. 8 is to be repeatedly used, that is, to be refilled after having been once used, a left hand external thread 25 on the container member 23 adjacent the collar 2? can be provided to cooperate with the internal thread 28 at the mouth end of the member 22, and in turn the member 23 might also be provided with a right hand external thread 29 to cooperate with the right hand internal thread 3!] on the collar 2? of the head 3 I. Consequently when it is desired to fill the two telescoping members 22 and they may be fitted into one another with the threads 25 and 28 cooperating with one another and the openings 24 closed by the inner end of the member 23 to shut off leakage from the interior of the members 22 and 23, and then after the members 22 and 23 have been filled, then the collar 21 of the head 3| connected to the right hand thread 29 of the member 23..

If the cost of the wall structure of the container 3 can be reduced to a minimum, certain advantages of course will flow from using a breakable container 3. On the other hand, if the liquid container can be refilled as would be the case with the embodiment shown in Fig. 8, certain other advantages may flow from the use of the telescoping combination shown in Fig. 8.

Furthermore, with regard to the embodiment shown in Fig. 8, it will be immaterial whether the threads 26 and 28 on the one hand are left hand threads, and the threads 29 and 39 are right hand threads on the other hand, or vice versa, since the operator will of course know in advance depending upon the relation of these threads whether the cap 3! must be turned away from, or toward, the operator to expose the openings 24.

The washer 25 obviously can be secured to the member 23 by a cement and/or an annular recess in one to receive an annular rib in the other as shown.

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claims.
